Product Details

Built for Lightweight Carbon-Spoke MTB Performance

Designed for modern Boost MTB wheel builds, this lightweight hub system is engineered specifically for carbon-spoke applications. The hub combines lightweight construction with race-ready durability, providing an optimized solution for high-performance MTB carbon wheel systems.

Full-Surface Ratchet Engagement

36T / 54T Ratchet System for Consistent Power Transfer

Compared with conventional pawl systems, the larger contact area distributes drivetrain loads more evenly, reducing localized stress while improving durability, engagement stability, and pedaling efficiency under demanding MTB conditions.

Patented One-Piece Ratchet Architecture

Integrated Design for Higher Strength & Reduced Failure Risk

ARC's patented one-piece ratchet design integrates the engagement structure into a single precision-engineered component. The system increases structural rigidity, reduces overall weight, and improves machining accuracy. The simplified construction also enhances long-term reliability while making assembly and maintenance more efficient.
